MODALITIES FOR REDUCING INTERLEUKIN-1 ACTIVITY IN DISEASE

The therapeutic advantage of reducing the activity of interleukin 1 (IL-1) resides in preventing its deleterious biological effects without interfering with homeostasis. As such, methods attempting to block the production or activity of IL-1 have now entered clinical trials. For example, IL-1 induction of prostaglandins is one target in treating disease, and drugs preventing the production of inhibiting cyclooxygenase have well-known toxicities because they block the normal synthesis of prostaglandins in many tissues. IL-1 blockading agents, in contrast, affect only that portion of prostaglandin synthesis due to elevated IL-1, sparing the synthesis of these molecules for homeostasis. Charles Dinarello reviews the unique pharmacological advantages of manipulating IL-1.
